[PATCH v2 052/113] efi: don't hide structs, enums or unions behind _t

Ahmad Fatoum a.fatoum at pengutronix.de
Mon Mar 4 10:59:37 PST 2024


Kernel coding style is to usually not hide the fact that a type is a
struct or enum behind a typedef. Follow that in the EFI code.

Besides being more descriptive, this also allows forward declarations,
so <efi.h> doesn't have to be included everywhere.

No functional change.
